Utility to read the contents of a vinyl file.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
/*
|
||
|
|
WARNING: This is a very naive plugin implementation
|
||
|
|
It is only meant for demonstation purposes.
|
||
|
|
For a more complete implementation, see: https://github.com/gulp-community/gulp-pug
|
||
|
|
*/
|
||
|
|
var { Transform } = require('streamx');
|
||
|
|
var pug = require('pug');
|
||
|
|
var vinylContents = require('vinyl-contents');
|
||
|
|
|
||
|
|
function gulpPug(options) {
|
||
|
|
return new Transform({
|
||
|
|
transform: function (file, cb) {
|
||
|
|
vinylContents(file, function (err, contents) {
|
||
|
|
if (err) {
|
||
|
|
return cb(err);
|
||
|
|
}
|
||
|
|
|
||
|
|
if (!contents) {
|
||
|
|
return cb();
|
||
|
|
}
|
||
|
|
|
||
|
|
file.contents = pug.compile(contents.toString(), options)();
|
||
|
|
cb(null, file);
|
||
|
|
});
|
||
|
|
},
|
||
|
|
});
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
### `vinylContents(file, callback)`
|
||
|
|
|
||
|
|
**Warning:** Only use this if interacting with a library that can **only** receive strings or buffers. This loads all streaming contents into memory which can cause unexpected results for your end-users.
|
||
|
|
|
||
|
|
Takes a Vinyl file and an error-first callback. Calls the callback with an error if one occur (or if the first argument is not a Vinyl file), or the file contents if no error occurs.
|
||
|
|
|
||
|
|
If the Vinyl contents are:
|
||
|
|
|
||
|
|
- A Buffer, will be returned directly.
|
||
|
|
- A Stream, will be buffered into a BufferList and returned.
|
||
|
|
- Empty, will be undefined.
